Oh, It's my first art and I'll make my future arts better then this try.

Thank you, for helpfull advice! When I did this, I will let you know 

P. S.

My english so bad..

Good work, I'm liked with the cavern ambientace, it's so combincent, also I think
there are too much colors on that... t-that dragon like, being more specific: if you
put more dithering like at this parts

   -click-

you'll make more sence on it and you can reduce the color count too creating
more shades with the dithering.
The piece looks amazing at 2x.
